Personally, I'm not too opposed to one-way federation, at least for the moment. They're not a large platform, nor particularly competitve with the more open Fediverse (for the moment). The lack of attribution on the other hand, is iffy, both in terms of giving OC creators proper attribution for their work, and in terms of reducing misinformation (IE showing .ml posts as standard news posts).

All that said, I don't think its a large enough issue to be concerned about for now. Give it like 3-6 months and see if things have changed (or if the problem has disappeared). This isn't like Threads where we have to worry about a billion dollar Embrace Extend Extinguish campaign. Who knows, if we're esspecially lucky, the site might grow into a better Fediverse alternative to Lemmy, or will grow and die in a way that sends positive users our way - something that would greatly benifit the Fediverse in it's current state.
